Hello CosmicWolfStorm. I have gone through similar stages and it is quite scary. Although I worked in a team I very detached and felt the only thing that kept me going was my job. It was the only thing in my life that gave me purpose. I don't take holidays as without the job I don't know what to do with myself. I have philosophised a lot but being of a very logical mind without fact and evidence it becomes an endless search for answers. Like your brother I loved physics and maths as there is always an answer. I did learn electronics years ago and could fix most things but studying theory was difficult. Your mind keeps going to the why. Even with basic electronic theory my mind kept wanting to go deeper right down to the atomic theory on why electrons and protons behave the way they do. I love computers I understand the logic but there seems to be no logic with people and while for most people that is not an issue it makes it difficult for me to connect.
